AUTQMATIC WATER ALARM AND REGULATOR.

SPECIFICATION forming part of Letters Patent No. 278,872, dated June 5,1883.

Application filed March 30, 18 83.

(No model.)

T0 66- u-hom, it may concern:

Be it known that I, NATHAN C. BUTLER, of Leipsic, in the county ofPutnam and State of Ohio, have invented certain new and usefulImprovements in. Automatic Water Alarms and Regulators forSteam-Boilers; and I do hereby declare that the following is a full,clear, and exact description of the invent-ion, which will enable othersskilled in the art to which it appertai'ns to make and use the same,reference being had to the accompanying drawings, which form a part ofthis specification.

My invention relates to an automatic water indicator and regulator forsteam-boilers; and it consists in the parts which will be hereinafterdescribed, and pointed out in the claims.

In the accompanying drawings, Figure 1 represents a portion of theboiler with my device, partly in section, attached thereto. Fig. 2 is ahorizontal sectional view of the device, showing the water-regulatingparts, (section through line 00 w in Fig. 1.) Fig. 3 is a plan view ofthe. float. Fig. 4 is an end view thereof with a fragment of thefloat-lever attached. Fig. 5 is an inside end view of thewater-regulating-valve stem, and Fig. 6 is a side view of thewater-regulating valve.

Like letters indicate like parts throughout the several views.

A is a cap provided with threads which cngage the threads in the casingA. B is a recessed projection on casing r and formed integral therewith.O is also a projection on easing A, similar in construction to B. D isthe inside of the casing, in which the steam and water valves arelocated. E is a plug having inside threads, by means of which theoutside threads on casing A are engaged thereto. The lower end of plug Escrews into boiler F. G is a block bolted to the inside of the boiler. His a rod fixed at its upper end to block G, and pivoted at its lower endto lever Iii I is a rod connected at its lower end to the adjustableblock J. L is the float, into which one end of the lever K is fixed. Therod I is adjustable on lever K by means of the sliding block J andset-screw 02, whereby the vertical play of rod I and valve 0 mayberegulated.

In the small letters, a is a locklever. b is an adjustable set-screw inthe top of rod I. c is the pivoted end of lever a. Said lever is let infrom the top, (in a dovetail, c,) and held in position by cap A. d isthe watera'egulating valve. 0 is the alarm or whistle valve, and ff arethe slides for the same. g g are nuts on rod 1, to secure valve 6adjustably. h is a reeesson theinside of casing A, in which the point oflock-lever a rests. c is the alarm or steam-whistle port. j is theinjector steamport. A: l are bolts for securing the block G to boiler F.I is the water-regulating-valve stein. m is a recess 01' mortise in thewater-regulating valve (7. (See Fig. 6.) '11- is a set-screw in block J,for adjustably securing the same on lever K. 0, Fig. 2, is the flattenedsurface of valve-stem I. p is a bearing for valve-stem Z. (1 representsthe parts upon which a wrench may be used. r is a bearing for valve (1.s is a movable stuning box, which secures the valve-stem Z, and t is thepacking-nut. a rep resents the stuffingspacc. "u is a set-screw forsecuring lever 20 to rod 1. no is the opening, Fig. 3, in float L, intowhich the'lever K is fastened. 1 is a pin uniting rod H and lever K. 2is also a pin, connecting block .I and rod I.

The operation of the device is as follows: hen the water in the boiler.gets low, the float L carries the float-lever K down, which draws downon the rod I and valve 6 and opens the alarm-port e, which permits thesteam to enter the opening B, and thence into awhistle attached thereto,but not shown in the drawings. The whistle will notify the attendants ofthe condition of the water. Then by turning the lever 20 in Fig. 2,which is secured to stem 1, the valve (1 will be raised and secured bythe lock-lever a, as shown by dotted lines, Fig. l. The injector is thenset to work, and the water forced into the boiler through the openings0, j, D, and 13.. As the wateriills in,

the float L is lifted, thereby raising the'lever K, rod I, and valve 6,and said valve, in rising, closes the port 6 and causes the whistle tostop blowing. The same upward movement forces the set-screw b on top ofrod I intocontact with lever (1, whereby said lever is raised and thevalve cl disengaged therefrom, which action permits the valve (1 to falland close the injector-port j.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. In an automatic water indicator and regulator forsteam-boilers, the float L, lever K, rod I, valve 0, and setscrew b, incombination with the pivoted lever a and water-valve (Z, substantiallyas deseribed, and for the purposes set forth.

In an automatic \va-ter indicator and regulator for steam-boilers, thefloat L, lev'er K, block G, and rods H I, in combination with the valves0 (Z and pivoted catch-lever a, substantially as deseribed, and for thepurposes set forth.

3. 111 an autol'natie water indicator and regulator for steam-boilers,the float L, lever K, bloek G, and rods II I, in combination with thevalves 0 (l, lever a, and easing A, prot'ided with ports ej,substantially as described, and for the purposes set forth.

4. 111 an automatic water indicator and regulator for steam-boilers, thefloat L, lever K, adjustable block J, boiler-block G, and rods H and I,in combination with the valves 0 (1, le
